For the M2 HSS tools, you can burnish a burr using the traditional burnishing rods that are used on the card scrapers. The triangle one works better. For the M42 and V10 metals, it is more difficult to raise that burr with anything other than a carbide rod. First one I made was a carbide drill bit that had been 'resharpened' and came in a small box with a bunch of tiny ones. A small diameter router bit will work as well.
I have been going back and forth on the burnished burr thing. For some reason, experimenting is a necessity to me...... Some times, the burr from the grinder seems to work just fine. I can turn it down and back up once or twice, then go back to the grinder. I can also hone a burr on the scrapers, using a medium or fine diamond hone. Lately, while turning some figured big leaf maple that is pretty green, I have been using both shear scrapers and NRSs on it, and the burr from a 600 grit CBN wheel seems to cut as well as just about any other burr. I need to get the 1000 grit wheel up on another grinder to play with it as well.
With the NRSs, I still prefer one with a 60/25 or 60/30 grind. It seems that the burr holds up a lot better if there is some metal under it to support the burr. The 30/30 ones just don't hold up as well.
The bass wood is pretty soft, and I wouldn't expect it to cut as cleanly with a NRS as the black locust would. Still, as some one said, a NRS is a high maintenance tool. I spend more time touching up that edge than any other tool I use. Also, it is just for fine finish cuts, not any type of stock removal.
